Question

Solve the formula for the perimeter of a rectangle with width w and length l,for the length P=2w+2l solve for l

Answer 1

Answer:Solve P = 2l + 2w for w.

The first step is to isolate the variable term, 2w.

Explanation:

Answer 2

`l=(P)/(2)-w`

Explanation:

we know that

The formula for the perimeter of a rectangle is equal to

`P=2(w+l)`

where

l is the length

w is the width

Solve for l

That means ----> Isolate the variable l

Divide by 2 both sides

`(P)/(2)=(2(w+l))/(2)`

Simplify right side

`(P)/(2)=w+l`

Subtract w both sides

`(P)/(2)-w=w+l-w`

Simplify right side

`(P)/(2)-w=l`

Rewrite

`l=(P)/(2)-w`
